ISL80019AIRZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL80019AIRZ-T7A is a synchronous buck regulator from the Renesas ISL80019 series, housed in an 8-WFDFN package with an exposed pad. It supports an input voltage range of 2.7 V to 5.5 V and delivers up to 1.5 A output current. The adjustable output voltage spans from 600 mV to 5.5 V. Operating at a fixed switching frequency of 2 MHz, it functions within a junction temperature range of -40°C to +125°C. The device features a load regulation of -0.2%/A and includes shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure the specific suffix matches design specifications as variants may differ in packaging or temperature grade.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact synchronous buck solution is required for single-output applications. The 2 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the input voltage range aligns with the system power source and that the 1.5 A current rating meets peak load demands without exceeding thermal limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL80019 family of low-quiescent-current synchronous buck regulators. It shares architectural similarities with other members like the ISL80019AFRZ-T7A but differs in operating temperature range and specific suffix designations. The series targets portable and battery-operated electronics where space and efficiency are critical constraints.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include ISL80019AFRZ-T7A and ISL80019AIRZ-T. Verify temperature range compatibility (-40°C to +125°C vs. -40°C to +85°C) and ensure pinout alignment. Cross-reference datasheets for minor parameter variations before implementation.
